Input: drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-13T22:43:19Z

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

Input: ad7879 - use device core to create driver-specific device attributes

2023-09-06T21:23:47Z

Instead of creating driver-specific device attributes with devm_device_add_group() have device core do this by setting up dev_groups pointer in the driver structure.

Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

Input: ad7879-i2c - Convert to i2c's .probe_new()

2022-12-02T22:53:44Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-226-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: ad7879 - return plain error code from ad7879_probe()

2017-03-01T17:42:44Z

With the switch to devm, there is no need for ad7879_probe() to return the touchscreen structure, we can use plain error code. This also fixes issue introduced with devm concersion, where we returned 0 on success (which worked OK since IS_ERR(0) would not trigger, but was not correct regardless).

Input: ad7879 - use more devm interfaces

2017-02-23T17:21:26Z

gpiochip_add now has a managed version, and we can remove sysfs attribute group via devm_add_action_or_reset (at least until we have devm version of sysfs_create_group). This allows us to get rid of ad7879_remove(). Reviewed-by: Michael Hennerich Tested-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Input: ad7879 - convert to use regmap

Instead of rolling our own infrastructure to provide uniform access to I2C and SPI buses, let's switch to using regmap. Reviewed-by: Michael Hennerich Tested-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Input: ad7879 - add device tree support

2016-03-08T18:51:18Z

Add device tree support for the I2C and SPI variant of AD7879(-1). This allows to specify the touchscreen controller as a I2C client node or SPI slave device. Most of the options available in platform data are also available as device tree properties, the only exception being GPIO capabilities, which can not be activated through device tree currently.
